We observed that the QPO frequency (\(\nu _{QPO}\) ) increases significantly as the source moves from epoch E1 to E2 and the total flux follows the same trend, which shows a positive correlation between the flux and \(\nu _{QPO}\)  [1]}. A positive correlation has also been observed between the photon-index and \(\nu _{QPO}\) . The changing QPO frequency could be connected to the inner edge of the accretion disk [2]}. If the total flux is connected to the mass accretion rate, this signifies that the inner edge of the accretion disk may move inward with an increasing mass accretion rate.
